Romeo & Duet
7pm, ITV
Following The Masked Singer and Starstruck, this is another talent show with a bizarre but cheery premise: singers try to bag a date by winning over fellow singletons with a karaoke song. The two matched couples then go off on a date to, err, learn a duet together, which they perform to the studio audience – and the pair who win the vote go on another date. Former Strictly Come Dancing professional Oti Mabuse is a woman we all want to be best pals with, so it’s worth giving her first presenting gig a chance. Hollie Richardson
Celebrity Mastermind
6.30pm, BBC One
If you know a thing or two about Jeeves & Wooster, pedigree cat breeds, Oasis and Ricky Hatton, you might fare well on tonight’s show. Pat Nevin, Anna Nightingale, Tom Malone Jr and Roo Irvine are the celebrities taking to the chair with their specialist topics, with Clive Myrie firing questions at them. HR
Titanic: Building the World’s Largest Ship
7.20pm, Channel 4
The Titanic was a magnificent feat of engineering, before Mother Nature crept up on her one icy April night. This one-off documentary uses original blueprints, unseen archive and special effects to tell the story of how 15,000 workers built this state-of-the-art floating city in Belfast. Ali Catterall
Britain’s Got Talent
8pm, ITV
After taking a year off, Ant and Dec bring back the long-running talent contest, with Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams in the judges’ seats. The first round of auditions sees a harmonious choir, a dog like no other and a very spooky man. Business as usual, then. HR
Hidden
9pm, BBC Four
Glyn is suspicious of his brother’s activities, as another death ricochets through the community. Cadi has a lot on: finding a replacement before she transfers, and awkward run-ins with Rachel. Will they work things out before next week’s finale? Henry Wong
Killing Eve
9.15pm, BBC One
The poised and blackly comic assassin thriller has always thrived on shocking and grisly deaths, and with the last ever episode looming it feels as if major characters are fair game. For now, though, Villanelle is lying low on the remote Scottish island claimed by her survivalist rival, Gunn, while the rudderless Eve seeks solace in some karaoke. Graeme Virtue

Mandy, 12.45am, Film4
This bizarre 2018 film is another staging post in the cult renaissance of Nicolas Cage – one that will probably reach its apogee this Friday with the release of The Unbearable Weight of Massive Talent, a comedy in which he stars as himself. Here, director Panos Cosmatos plunges Cage into a phantasmagorical revenge horror – part giallo, part S&M nightmare. He plays lumberjack Red, living in rural bliss with artist partner Mandy (Andrea Riseborough), until a messianic cult turns up and its leader, Linus Roache’s Jeremiah, takes a shine to her. An exercise in extreme gothic style, it’s gory and gobsmacking, with a near-silent Cage at the top of his psychotic game. Simon Wardell
I Blame Society, 11pm, Film4
Gillian Wallace Horvat’s gleeful mockumentary is part satire on cinematic authenticity and part Lady Vengeance-tinged horror. After being told she’d make a good murderer, struggling but overly self-confident Los Angeles indie film-maker Gillian (Wallace Horvat) documents herself putting the theory into practice, step by ever more bloody step. You can see all this as a metaphor for the cut-throat nature of the movie business, but it’s also a glorious black comedy about finding your calling and really going for it. SW
